Application filed February This invention has for its object toproride the aw bearing or jaw for receiving the trunnion of a beam roller or the like, as one from which cloth, warp or other wound material is to be unwounth with a simple but ethcient means for releasably retaining the trunnion of the beam or equivalent in the bearng, or against jumping or working out of the same as an. incident of the pull of the fabric.

In the drawings,

Fig. 1 is a rear elevation, Fig. :2 a side eleration and Fig. 3 a plan of a jaw hearing or jaw embodying the invention, the trunnion lock being shown in open position;

Figs. l and 5 are side elevation and plan of the jaw with the lock in closed position;

Fig. (3 is a side elevation of the locking de vice; and Fig. 7 a sectional view thereof on the line 7-T, Fig. 6;

Fig. 8 shows a rear and a side elevation of the jaw properthe View in r ar elevation shows the jaw proper broken away on the dotted line of the side elevation; and

Fig. 9 is an inside and a rear elevation of the bearing piece for the locking device.

The aw hearing or jaw comprises the jaw proper a and a bearing piece 5. The jaw proper may be the jaw part of the frame of any existing machine in which roller, beam or the like is journaled. a is its recess for receiving the beam trunnion. Parallel with the axis of the trunnion when journaled in said. recess the jaw proper is formed with holes o The bearing piece or bearing 2') is a thick disk formed with a radial recess 7) and also with a peripheral flange b at one side. This hearing or bearing piece is socured to the jaw proper by machine screws (Fig. 1) extending through the holes a and beingscrewed into holes tapped into the hearing. The recesses of the jaw proper and bearing coincide when they are assembled as shown in Fig. 3.

r] designates the trunnion of the beam or other part to be journalcd.

The locking device consists of a disk-like member 6 having a radial handle 0. Its central portion is cut away concentrically with its axis as at 6 so as to fit the periphery b of the bearing 7), and at a point about from the handle the disk has a notch (a communicating with the opening 6 of the disk.

The parts are assembled by fitting the locking device 6 to the bearing 3), which will bring the flange of the latter bearing against 19, 1925. Serial No. 18,429.

one side of the disk portion of the locking device, and then the bearing is secured to the jaw proper by the screws 0 as already stated. The locking device will then be confined be tween the ja v proper (i and the flange 7) of the bearing, and by means of its handle c it can be turned back and forth on F) as an axis to bring its notch 6 either into or out of coincidence with the recess of the jaw or jaw bearing; in the former position. the trunnion (Z may be introduced into the jaw and in the latter position of the locking de vice said trunnion will be retained in the jaw as will be obvious.

So far as I am aware it is new in this art to arrange a locking member, having a notch to receive the part to be journaled and revoluble on the jaw around said part back and forth to bring its notch into or out of coincidence with the recess of the jaw, at one side of said jaw. In the actual construe tion while the locking member is revoluble around the part (Z to be journaled, it is eccentric with respect to the axis of said part; the object of this is to bring the inside periphery e of the locking member when in the locking position close to said part (so as to confine the latter against undue looseness in its bearing) and yet produce a simple and substantial jaw construction.

It is desirable to limit the back and forth movement of the locking member, so that at one extremity of such movement its notch will coincide with the recess of the jaw and at the other extremity it will be out of coincidence therewith; it is also desirable to hold the locking device in either of these positions. Hence the following construction: The bearing; Z) has a radial bore 7 in which is a detent g backed by a spring it, this detent being a ball or equivalent affording a rounded outer surface 9. The member 6 has its opening 6 formed with two notches i spaced apart about 90, the relatively remote sides 71 forming abrupt shoulders and their opposite sides 2' forming cams as shown in Fig. 6. By this construction the locking device when moved in either direction will come to a positive stop by the contact of a shoulder 2" with the detent g and by the seating of the detent in the notch 2' the locking device will be held in its new position except sufficient force applied to the handle 6 is exerted to cause the surface 2' of the notch to cam the detent inward.

Mere hooks to hold a shaft or other part in till Ill)

its bearing are known. My invention in part distinguishes from such devices in that the locking member has an opening (6 to receive said part and through which also extends the axis of rotation of the locking device.

Having thus fully described my invention what I claim and desire to secure by Letters Patent is:

1. In combination, a jaw having a recess to receive the part to be journaled and a locking member journaled on said ja and having an opening to receive said part and a notch narrower than and extending to said opening and being revoluble on the jaw around said part and also around an axis extending through said opening to bring the notch into or out of coincidence with said recess and which axis is offset with respect to the axis of rotation of said part in the direction in which the latter is introduced into said recess.

2. In combination, a jaw member having a recess to receive the part to be journaled and a locking member having a notch to. receive said part and revoluble on the jaw member around said part to limits where said notch will be either in or out of coincidence with said recess, one of said members having a spring dctent and the other notches arranged to receive the detent at said limits, respectively, the relatively rei'note sides of the notches forming positive stops for the detent and their nearer sides forming cams engageable by the detent.

3. In combination, a jaw including a jaw proper and a hearing at one side of the jaw proper, said jaw proper and bearing having coinciding bearing recesses to receive the part to be journaled, and a locking member embracing and revoluble on said bearing around said part and having a notch to receive the latter adapted to be placed in or out of coincidence with said recesses when said member is rotating.

In testimony whereof I affix my signature.
